SD FAT32 partition is very slow

I stated this question before, googled and tried numerous things to solve it - no luck
I debranded the phone and rooted - used a goldcard (the same SD card I am speaking here about) - originaly Android 2.1 T-Mobile CZ . The SD is Kingston 16GB Class 10.
There are ppl (including me), who have a problem with copying files from PC to the SD Card. It's about 1.5-2MB/s . With my original 2.1 ROM the speed was 7-8MB/s .
When copying the other way - SD Card --> PC - 4,5-5MB/s . Before it was 11-12MB/s .
Just to be accurate - it's not only a mass storage problem. When Benchmarking the SD Card using some Android Apps - same speed :-(.
Read Speed - 5-6MB/s
Write Speed - 2-3MB/s
The card has 3 partitions:
- Swap with 384MB
- EXT4 1536MB for APPSD
- FAT32 ~ 14GB
Tried numerous partition settings, formatted the card all over and over again. Only the FAT32 partition is slow - EXT works well.
Formated with the "ClockworkMod Recovery Image", "Linux", "Windows 7" . Used even slow formating .
Any ideas why ?

Its no problem any rom or any card or any partition
Its problem AFTER root.
Any rom, any card after root, slow write to sd card via phone.
If unroot, all ok.
No diference partition FAT32+ext or only fat32 ... after root slow.

Even if using a cardreader - the speeds are the same...
Thats what brings me into thinking - it has nothing to do with a rooted phone - it has something to do with the rooting process - it corrupts the SD card somehow

I must disagree on this.
When I put the Card into my CardReader i got fullspeed on the other partitions.
Haven't unrooted yet though....

Well, i think that might depend on the sdcard then. Just changed my card from a 8GB class 4 to 16GB class6.[Kingston] With a cardreader i really get the speeds to expect. Wenn tranfering through a usb-cable speeds decrease.

Yes, the speeds through the USB cable are allways a little but slower - but it's still kind of the same speed - see the difference - 2,3MB/s Mass Storage VS 3,1MB/s CardReader

Well, if you are unrooted and thus not running any form of legacy A2SD, I suggest it's related to your EXT partitions.
IMO, any form of swap is going to slow your phone down, and this may be the case if the system is trying to buffer disk I/O in "memory", so I'd definitely be inclined to try deleting your swap space for starters to see if it makes an difference.

Dave

That might be it.. I have no swap and a ext3 of 756MB. Maybe the OP shouldt try that.

In my case it's the A2SD+ that slows down the card

I am using the "SD Card Speed Test" app on the phone. - u can find it via Market...
Also - having no SWAP doesn't solve anything - as i said - tried all partition settings.

I have exactly the same problem. I think, A2SD+ causes that. When you copy a file via USB, your phone use EXT partition meanwhile(I guess it only mounts FAT32 partition). So that makes FAT32 partition slower. And when you use Card Reader, it doesn't use EXT partition so copying speed doesn't slow down. It's just my opinion of course.

I dont have ext, now. Only FAT32 (without ext) and slow.
Its no problem USB. If tested internal speed in phone (without usb) via SD Card test from market .. result slow... above picture
Everybody with rooted phone have slow sd card transfer to fat32, but everybody tuning wallpapers, mad

Hmm. It was just gueesing
I think the devs might look into that. It's important issue imo.

This is a known issue. There's a thread somewhere in here about it, but I can't find it anymore.
I average like 10/ Mb/s vs 7 Mb/s using cardreader with different write sizes. On my OpenDesire 4.0.10 I get about a steady 2Mb/s on both write and read.
* Problem did not exist pre-root on 2.1
* Problem is not SD card itself, except of course if you got a card that performs badly. The original one (class 2, 4gb) performs just as badly as my Class 4 16Gb. They perform really well using a cardreader though.
* Have had the problem since rooted and ran DeFrost in early june. I've only used Nexus Froyo ports until AOSP ones started popping up, so I can't speak for any other than DeFrost up to 2.3 and OpenDesire 4.0.10.
* Does not have anything to do with App2SD from what I can find out. Either native or modded. Why? I've never used it until two weeks ago.
* Problem surely must be Android related itself (maybe a bug? Any problems on the Nexus?), because the write/read speed is just as bad for the phone vs SD card internally as it's over USB Mass Storage mode.
I don't get it really. It's weird. Some of the devs surely must have gotten irritated about this weird behavior and investigated? Maybe we can call Kali to our aid this time? He's really been our savior in other instances and I suspect it's gonna be a simple fix in the end.
Questions which may make our quest easier:
* How's a original phone, non rooted HTC Sense 2.2 ROM performing?
* How's a rooted phone (Unrevoked, Clockwork, AmonRa etc), but nonrooted more or less original HTC Sense 2.2 ROM performing?
* How's a rooted phone, with rooted/modded HTC Sense 2.2 ROM performing?
* How's a fully modded, full of bloatware Sense mod yadda yadda performing? (you get my point)
I'm running OpenDesire 4.0.10 which is AOSP with quite a few bits and bobs, so I know how that performs. It uses a fork of Cyanogen Passion kernel, and I suspect the rest of the AOSP ROM's does more or less the same. If you got one that is not based on Cyanogen, or a Cyanogen that performs really well, please tell and post your results. Simple average reports with some details of your ROM. No super duper accurate over time diagnostics crap.
Could it be the root process itself that causes the problem? A glitch somewhere in a boot driver?
I switched from fake-flash (back in june version) to a Unrevoked AmonRA two weeks ago. Problem remains. So, got no clue there.
I'll do a speed test in AmonRA Mass Storage Mode tomorrow to see if problem is present there also. Then surely there must be something weird going on.
EDIT:
Please. Don't ask me how to benchmark your SD card (no windows buffered speeds here!), what the difference of/in ROM's are, which kernel is which, who's who etc. If you know what I'm talking about you'll also know what to do (enough ranting from me).
EDIT2 (outside main OS):
In AmonRA Recovery Image (installed with Unrevoked), speed is just as low as when android itself is loaded.
This worries me. Kernel related or not? Maybe AmonRA kernel just isn't configured for high speed storage and we're sidetracked.

In AmonRA Mass is speed low, identical, but without burst lag ( < 2MB/s )

[Q] Internal-External Memory Swap: useful or not?

Hi
I have a Samsung Galaxy W, and you know that this device has such a little memory for apps and games.
I bought a 16 gb class 10 external sd and I was wonder if the memory swap mod could be a really useful operation.
I'm not usual to install lots of applications and games, (I really use only social apps) however sometimes I like to play some heavy-data games. So I need a help: do you suggest me to keep the sd as a default external memory, maybe trying to move the heavier apps in this external space with link2sd and other stuff, or it would be better to make the swap and then make the sd recognized as internal memory?
I read that sometimes the swap operation causes lags and some other stuff, so I need your opinions and suggests.
Thanks in advice

Some custom ROMs automatically swap /sdcard/ with /sdcard/external_sd/
You could try that, it's a great solution IMHO.
Did you try "GL to SD(root)"? Download it from the market... It just mount the external SD as the sdcard, but temporarily. And it also moves game data to external SD.
Sent from my GT-I8150 using XDA on CyanogenMod 9

Also bugs me as well. I just bought 32gb class 10 card and i am using cow bionic 2 rom. But i already changed the vold.fstab folder back to stock. I would be the same not a heavy app storer. If i dont use the app any more i delete it.
But supposedly if you have a class 10 card you should not experience any lag if you have the swap done?? How true this is i dont know

maybe i'll find this useful for heavy data games like generation of chaos or other apps/games that install themselves on the internal storage and not on the sd card, other than that, i seriously don't know what other advantage it can provide

Of course, swapping is a good solution for huge games data storing on external sd and u own a class 10 sd card which is fast enough for swapping. However, this may cause problem when u want to remove sd card as most of the apps are stored on it.
GL to sd is a better solution to me personally. I wrote a similar script instead of using GL to sd. This mounts certain paths to ur external sd card while keeping other important apps such as launcher, theme, widgets, on the internal sd.

Care to explain about the script you wrote. Also whats GL?? I wouldnt use any big games so no point in me swapping. But if any roms i flash to the phone has this done ill not bother changing it back to stock. Also is class 10 not the highest micro sd card you can get??

Yes, class 10 is the fastest writing speed for MicroSD at this moment.
I used script manager to create a script for mounting and give it SU and set it on boot. It is very simple.
Create a new script file and type the following:
(I used the Android folder as example)
Code:
mount -o bind sdcard/external_sd/Android sdcard/Android
This is for gameloft
Code:
mount -o bind sdcard/external_sd/gameloft sdcard/gameloft
After creating these, u need to cut the files in Android or gameloft from internal sdcard and paste them to the new location on external sd. Leave the original folders empty.
Remember to set them "boot" and "su".
enjoy
Edit: if u download any other games that stores its data in Android folder, it will automatically move to ur external sd card as the script has mounted the path to external sd since every boot.

But, in a swap situation, on the Wonder, Apps are not moved to External SD Card........
without swap they are moved to /sdcard/external_sd/.android_secure folder
with swap, moved Apps should be on re-mapped internal SD, so removing SD Card should not have any effect on Apps...
of course App Data should be on External [Removable] SD Card...re-mapped as /sdcard
It seems to me, for game players, Game Loft, etc.....Gl to SD is the ideal solution....****see also EDIT below****
Video for Wonder Here:
****EDIT: Just to say, yewsiong script looks good for gamers, etc.....****

It's pretty useful if you're an avid gamer. Some games usually reach 400mb+. But if not, you could still use it for storing music and videos.

IMHO I see no cons whatsoever in performing the SD Card swap, just pros. I got my 32Gb Class 10 just for the swap... Check my signature links to see what I've done to my SGW...

Hi,
I followed the method outlined in your signature (http://latgale.co.uk/?p=70) and now I can see about 15GB (I have a 16GB class 10 SD) available for apps on SD.
However, when I try to move an app to the SD by using App2SD, the app doesn't go to the 15GB partition. How do you do?
Thanks a lot.

Yeah... This is something I haven't found a solution for. Whenever you try to move an app, it goes to the USB Storage. Since we swapped memories, the app will be moved to the 1.7GB memory. For me it'd be great to have everything in the Micro SD card, the 1.7 GB memory is useless to me...

Yeah, that's a real pity! :crying:
I wonder what's the point of doing so, if the memory available for the apps still remains the 1,7GB partition... why swapping partitions then?
Do you have any idea if there is any ROM that lets you install apps in the "bigger partition" (the 14,3 GB according to the example above) or are you aware of any other possible solution?
Thanks.

Yep, that's exactly what I would like to have!
I bought a 16GB card to install many maps and games, but I quickly ran out of memory so I cannot add anymore apps (without removing already installed apps of course).
That's why I would like to use my SD card for apps - if possible of course!
And it's a pity I have 15GB free (for what? Just my music/video/pictures?) and I cannot use this space for apps.
What are the other ways to achieve this you mentioned?
It'd be really helpful!

Storage, what its designed for. Its no different than partitioning your hard drive in your computer. It just splits the storage volume up. Older phones with less internal app storage people would partition their cards to use a2sd and gain extra app space thats it nothing else flash memory is like rom(random operating memory) a space for storage and containing filesystems. RAM (random access memory) is the space applications are executed in, it has a much higher read/write speed allowing the application to function without lag. You could put a swap space on sd but it still isn't RAM it will only be utilized by idle applications to hold them open while they are dormant. Android is already efficient in killing open apps to free RAM when needed and swap doesn't really work the same way it does on a pc. 9/10 times andorid kills the app instead of utilizing the swap space.

I don't know if I really wrong, but it's the proof. Here's the step-by-step how that man explain to increase the RAM using micro SD.
*)It's originally in Indonesian Language, but I translate it to English..
First Version:
1. first backup the data on your SD Card. because the SD Card will be on Delete and Format Partition.
2. Download Software for making partition, you can use the Mini Tool Partition Wizard or EASEUS Partition Master
http://www.partitionwizard.com/free-partition-manager.html
3. Install MiniTools on PC
4. Connect your phone to PC
5. Delete partiton SD Card and then click Create Partition
6. Because I just 2GB SD Card so I only make 2 pieces patition. First Partition Using Ext3 format. Partition for linux at 500Mb. Used to install / move apps from phone memory to SD Card
7. The second partition the rest of the first partition, the FAT32 format. Used to store data such as office, mp3, videos etc..
8. If the SD Card Has a fairly large you can make a 3rd partition Swap format. Swap partitions are used to support the work of RAM. and a swap partition usually made ​​of 2 times the RAM.
10. When finished click APPLY on the top left corner to execute the partition that has been created.
Second version:
Material that you need:
1. dtapp signed
2. A2SDGUI
3. Have already partitioned sdcard
The steps:
1. move the material to the sd card
2. Enter to recovery, choose mount storage and change to:
_unmount / caches
_mount / data
_unmount / system
_unmount / sdcard
_unmount / sd-ext
3. If you done, back to start menu and install dtapps2sd cwm-2.7.5.3-beta04-signed.zip who already downloaded earlier. . finished and reboot the system.
4. Then install A2SDGUI open a2sdgui zipalign on boot and set swappiness 60-65. Then move to Dalvik tab, select the Dalvik cache on sd ext, click move. allow it to reboot. See Picture.

5. Wait wait until the reboot is complete.
6. After your phone ready, enter terminal emulator type this command.
_su
_a2sd datasd
let it reboot
7. If done, it can be checked in titanium back up.
And this the result.
Third version:
1. Download Application RAM Expander
2. Your phone has rooted.
3. The SD Card has swapped.
4. Install Application Ram Expander
5. Open RE , choose Optimal Value then swap active
6. Ram so relieved now

I think what you are talking about is swap. Which this phone has more than enough RAM that swap is not needed. Swap partitions kill SD cards anyways.

even if you could, tricking the OS to use sd as ram would be awful.

its impossible to use an sd card as RAM. anything that tells you otherwise is lying. the only way to get more ram is to buy a better phone.

Unable to move apps on SD Card after 6.0 update

Hello,
After upgrade and factory reset and micro-SD format, I am unable to move apps on the SD Card of my LG G4 H815.
I know that some can't be moved, but some can, and I am unable to move some games that before I was able to move, because I don't get that option. I also tried with a different micro-SD, although the card worked just fine before the upgrade.
I just don't get that options - I don't even get the option to format the external SD as phone memory, as I know it should do.
I wanted to post screenshots but I can't, because I'm a new member, so I'll try to explain:
- I go to Settings - Apps - choose a game - storage - there are only 2 options, clear data and clear cache
-I go to Storage - SD Card - settings - (here I have only Eject and Format, and if I choose Format, the only option I have is format as portable storage)
Did anyone faced a similar problem? I digged around bout couldn't find anything like this.
Thank you

I have the same problem, wen i upgrade to 6.0 i have some games with the option to choose were the data goes, less than 5.0 but i can move few.
I hard reset to stop batery drain and now i cant move any data from apps to SD card.

Same problem here! Even link2sd doesn't works...

Did you format your sd card as portable/external? How did you format your partitions and what formats when you tried link2sd?

Just tried it link2sd works for me using Fat32 on first partition and second one ext2. It had to reboot once but I guess it has something to do with my systemless root as it simply dissappeared and I had to reroot again.

The only option is portable in the format on the phone. I was under the impression under marshmallow you would be able to format either to portable or internal.

Just checked move 2 sd isnt showing up in options my guess it has something to do with the new internal/external feature, did not test with link2sd only linking tested and that works for me. I guess that you can only format as external is caused by stock rom. After all I have read internal seems not to be a good choice for mobiles with enough internal storage

Link2sd was formatted as ext4 that worked on lolly, but the big problem is I formatted as external (only choice) and the "move to sd" button does'nt appear at all! Maybe I should format all the sd as ext4? In a nutshell the 20B is using my sd as an otg storage, can read and write, but not considered by games and so (luckily the camera srill save pics and vids on sd).as far as I can see there is only thi thread and we are the only one thata have this problem!

I search about it and seems, LG dont implement 6.0 feature to use SD as internal memory if SD card have the minimal speed requirements

Try ext2 on second partition then it will work. I only have the problem that it wont mount at reboot, I always have to wait after complete boot and some time more until it recognizes second partition and mounts it. Perhaps an issue with systemless root (supersu 2.65beta) I am using but as long as no system apps are linked there is no problem with this (and I dont reboot often)

Ext4 on link2sd used to work, but in 6.0 (20b) it looks like I deleted a lot of "trash" so I was able to reatore all the app without link2sd and I would like not to use it, just to move app to mi samsung64gb sd to save other internal space for the future.I know it doesn't move the complete app, but one day maybe you will need even just 5mb...never say never....and one day you may need even just 5mb of internal memory...never say never... anyhow it store lictures in my sd, so I'm really afraid is about a limit of the rom or the memory card (I miss the format as internal memory too, while someone has that option on G4, am I wrong?) I have the classic silver 64gb samsung micro sd not the ultrafast version I used to make 4k vids on my old S5!

I personally bought link2sd as the old move 2 sd didnt work well with my samsung galaxy tab s, most apps crashed but using link2sd they worked (not all but most of them). As for SD card I have a sandisk ultra 128GB and no problem recording 4k to it, I use the mod with the highest bitrate from the forums here

I was talnkig about my SD not to say if I can record or not 4k (we are off topic here), but just to say that is NOT the ultrafast that samsung requires for recording 4k video without modding.
I just mean that now I have a "Samsung MB-MP64D/EU Micro SD XC EVO, UHS-1, CLASS 10 orange/wite" not the "Samsung MB-MG64D/EU micro SDXC Pro 64Go Class 10 UHS-I silver".
The latter was required by samsung to record 4k video=superfaster compared to the hal priced one I have.So, MAYBE, the SD does the difference in Marshmallow, it detects the kid of SD and allow us to use it as internal memory and/or to move the apps on the sd without the Link2SD app (for the record, I used ext4 withou problem with lollypop, now Link2SD doesn't find the partition, I won't waste time trying other ext till my phone will be full).

[GUIDE] Configure SD card as internal storage in Marshmallow on LG Spirit [H440n]

Hello,
Yesterday I've upgraded software on my LG Spirit to Marshmallow (PL/PLAY). Unfortunately it's not possible to root it yet, so after few hours I started to miss Link2SD functionallity. :crying:
I found that Marshmallow shall offer formating SD Card as Internal storage. Unfortunately, it seems that LG disabled this feature. But... it's still possible to enable it via ADB SHELL! :victory:
Here is how you can do that:
Backup your data - for sure, you don't want to lose all your data stored on SD. If you want to lose it, feel free to skip this step
Enable USB debugging mode in developer settings - to enable developer settings you have to tap 5 Times on the build numer.
Open ADB Shell - just open command prompt (Win+R => Type "cmd" => Click "OK") and navigate to your ADB directory (ex.: "cd c:\adb\"), then use "adb shell" command to start shell.
List avaliable disks to get disk ID. It can be done with following command:
Code:
sm list-disks
You will get your SD Card ID (ex.: disk:179,64, which will be used in next step.
Format your SD card by typing below command. Remember to put correct Disk ID obtained in previous step.
Code:
sm partition disk:179,64 private
This command will cause that whole card will be formated as Internal Storage. If you want to use only part of SD as Internal Storage and rest as standard Removable Disk, for example 50:50, you can use command:
Code:
sm partition disk:179,64 mixed 50
Check your storage settings and enjoy additional internal storage!

Cool! Gonna try it soon!

Thanks for sharing,it works

I've been doing this since I installed marshmallow but I'm not sure if it works properly. Every app or app data remains in the internal storage unless I manually move the app to sd. Is that normal?

Can this work with any Android device having the marshmallow SW version.

Applications will move to sd card with all their files?
Będzie przenosić całe aplikację? I czym się to różni od przenoszenia na nie sformatowaną kartę?

What is the difference between formatting the SD card as internal storage and transfering the app from internal to SD?

@SteSko: What class card did you use? I've read people over the internet complaining that the write and read are much slower than internal even with Class 10 cards, and that you need a UHS-I card for storage adoption to make sense.
I would appreciate some info on your performance so far. Cheers!

To be fair, class 10 means nothing these days. To qualify as class 10, the card has to have a minimum of 10mb/s transfer speed, while internal memory is uncomparably faster.

As far as I know, UHS-I guarantees the same measly 10mb/s, just like Class 10. So even if the technology is better overall - which it is - it's not an actual promise, since it only maximizes the speed potential. People have been experiencing wildly differing transfer speeds on various devices even on those cards, because things just didn't stack up properly. That's why I'm so curious how folks are faring with our device.

To return back to normal use this
sm partition disk:179,64 public 100

Just a heads up - my card died as I was trying this. Probably because it was old, and not because of this, but I just wanted to let you guys know. ( The card died right after the command, but I can still see the single partition on my computer , but I can't manipulate the files in any way, and it's really intermittent. )

Hi guys, i have a problem. I adopted my sd card as mixed storage, used 20gb for internal and 10gb for external...today i factory reset the phone and now i cant see the adopted storage only this 10gb external. the problem is that i cannot format the card to be 32gb of external. i basically have 32gb sd card with only 10gb usable because the other part was encrypted by phone and now i cant see it anymore cuz probably the encryption key was lost after reset. i tried using adb shell to list volumes but it says 'private disk mounted null' and 'public disk 179,65'. Also, when i list disks in adb shell it shows me 179,64 and i cant partition it to private with 'sm partition disk:179,64 private'...anyone has a solution to formatting the card to be just normal card used as external memory? Also, i tried using minitool to manually partition the card, there i can see there are 2 partitions, this 10gb partition that is formatted as FAT32 and the 20gb that says 'other format', i believe it is Ext4 but i tried to manually format that partition to Ext4 hoping my phone would recognize it but no use...any thoughts?
i tried sm partition disk:179,64 public but it didnt help...it seems like the phone sees that 179.64 disk as potential adopting disk but on the other hand disk is alredy protected by that lost encryption key and since i factory reset the phone i cant go and dig it up

Hmm, guys, I did this in the past and if I recall correctly you should click on the SD card in the storage menu, go to the options and select "Migrate data". I may be wrong, though.

Hello, I followed the directions, and partitioned the sd.
Now how does the thing? I have the memory almost full, the bar is red and there is the danger signal, once the internal filled automatically fills the sd partition?
Thanks

once you partitioned sd it became your primary storage. this is not expanding but replacing storage..if you have 8gb internal and use 32gb external you wont have 40gb, you will have 32 because once you adopt the external sd as storage it will replace the internal..what you can do is go to settings->storage->internal storage->migrate data to transfer your apps from phone memory to sd card and all future apps will be installed directly to sd
